Street lighting chromatic aberration reason:
♦LED brand
Different LED brands have different lighting color, some of them are more yellow , some of them are more white color.
♦LED lighting color
The CRI value is more bigger, the yellow colour is more obvious. It’s just a matter of extent of yellow colour more or less . If the yellow colour extent is less to be accepted, then it’s ok to use it.
Three solutions to reduce the lighting chromatic aberration
►Changing your LED brand
Lighting companies can change to use other brand LEDs like Lumileds LED, Osram, Cree, Samsung etc.
► Making lens optical surface frosted
Optics manufacturer can reduce the LED lighting yellow color by making the optical surface to be frosted.
Asahi frosted optical surface lens:
60° Wide Beam 4x6 Flood Light Lens With IP Protection
173mm Dia 3x8 Zhaga 60degree Outdoor Sports Arena Lens
60degree beam angle 96LEDs highbay light lens for outdoor court lighting
►Optimizing the lens distribution curve
Optical lens manufacturer can optimize the distribution curve to reducing the lighting chromatic aberration through modifing the lens mold. Of course the lens diagram must satisfy the road scenario requirements at the same time.
